需求
1、该拓扑为公司网络,其中包括公司总部、公司分部以及公司骨干网,不包含运营商公网部分。
2、设备名称均使用拓扑上名称改名,并且区分大小写。
3、整张拓扑均使用私网地址进行配置。
4、整张网络中,运行OSPF协议或者BGP协议的设备,其Router-id值为设备名数字号,例如R1的Router-id为1.1.1.1、
5、OSPF路由宣告部分选择接口宣告方式,例如192.168.100.1 0.0.0.0;BGP仅宣告用户网段。
6、IBGP部分使用环回建立邻居,EBGP部分使用直连链路建立邻居,所有运行BGP的设备都需要建立邻居。
7、R1、R2、R5、R6、R7、R8、R9、R10需要配置环回接口,环回接口IP为设备名数字号,掩码为32,例如R2的环回接口为2.2.2.2/32
8、所有PC的IP地址均手工配置。
公司分部:
1、PC5和PC6属于不同VLAN
2、SW4是一个二层交换机
3、SW3是一个三层交换机
4、R9是分部出口路由器
5、分部使用OSPF进程200达到分部网络全网可达
6、公司分部出口设备运行BGP协议连接骨干网络,AS号为100
7、因AS-PATH属性原因,总部与分部路由会学习不到,使用命令如(peer 10.10.10.10 allow-as-loop,仅在总部与分部设备上配置即可),将允许AS号重复。
公司总部:
1、交换机为二层交换机
2、PC1和PC2属于一个网段,PC3和PC4是一个网段
3、R3和R4分别是下方PC的网关路由器
4、为保障公司总部到骨干网络的连通性,公司总部使用双路由器双出口的方式接入骨干网
5、为保障公司总部网络内部具备负载,R1、R2、R3、R4设备均作为设备冗余,并使用全连接的方式进行路由选路
6、总部内网使用OSPF进程100达到全网可达,OSPF需要宣告环回。
7、公司总部双出口设备运行BGP协议连接骨干网络,AS号为100
8、因为R1和R2重发布时会出现次优路径,需要修改BGP路由优先级,使用命令(preference 140 255 255,仅在总部设备上配置即可),配置位置在iPv4-family unicast中。
公司骨干网:
1、为保障公司网络连通性,骨干网络考虑设备冗余操作,连接总部使用双路由器,骨干网络部分路由器之间使用双联路方式
2、骨干网设备运行OSPF协议达到骨干网全网可达,进程号为10。
3、骨干网设备运行BGP协议,AS号为200。使用全连接方式建邻。
优化:
1、为达到分流互备效果,公司总部业务部访问分部流量走R1,R2做备份;公司总部工程部访问分部流量走R2,R1做备份,并要求来回路径一致。
2、公司总部双出口流量均流向R5,R6做备份。来回路径一致。
3、OSPF重发布时,更改类型为Type-1
4、所有策略名称为policy-1
5、更改开销时,全部更改为10
